i Application filed February 21 1925. Serial L170. 10,759.

This invention relates to typewriting machines wherein the operativemechanism is mounted in a frame, said mechanism including a platenrotatably mounted in a to and fro movable carriageat the rear and top ofthe frame, typebars striking rears wardly against the platen and thetypebars actuated by fulcrumed levers arranged with finger keys, andit-is the object of the invention to providemeans to adjustably supportthe machine to variably position the-platen to change the focal distanceof the line of writing on the platen relative to the visiono'f the-operator.'

It is a further object of the invention to provide means to tilt therear portion of the machineupwardly at an oblique angle to thehorizontal and retain the machine in adjusted position during theoperation thereof.

Another object of the invention relates to an arrangement of finger keysconnected to the typebar actuating levers,- whereby.

when the machine is in'horizontal position said keys will assume aposition in substantially the same horizontal plane and inclined at anangleoblique to the horizontal, and as the machine is tilted to changethe focal distance of the line of Writing on the platen said keys willassume a banked for mation with the face of the keys extending in ahorizontal plane.

Other objects andadvantages will hereinafter appear. a

In the drawings accompanying and forming a part of this specificationFigure 1 is a side elevation of a writing machine show. ing anembodiment of the adjustable support for the machine whereby the rearportionof the machine is adaptedto be tilted upward to variable angularpositions to. the horizontal, and showing the'machine adjusted to itsuppermost position, only so much of the operative mcchansim ot themachine being shown as is essential to an understanding of theinvention.

Figure 2 is a vievv similar to'Figure ,1 showing the machine adjusted tohorizontal position. J r r F g re; 3 is p a away,

S milar characters or reference; designate like parts throughout theditferent v ews l of the drawings. a In carrying out the emhodin lentvof the mventlon illustrated in the drawings the operative mechanism ofthe writing machine is mounted in and carried by frame F the; bottom ofthe sides and rear end 0t which are preferably flat, as at 8 althoughthis is not absolutely essential whereby the machine may be supportedwith the bottom extending in, a horizontal planelin contiguous relationto a supportthereforf The machine carries at the rear. and top, theusual'platen 9 rotatably mounted carriage to have to and frolongitudinal bars 10 having .type carrying heads 11' mounted thereon areadapted to be 'moyed from a position of rest 12 rearward against theplaten, as; shown in dotted lines in Figures 1 and'2. The typebars 10are an rangedin slots'of a segment" [18, as in Figure 3, and actuated byfulcrumed levers "14,- extending in parallel relation, and havinganoperative connection with the typebars, shown as through a rack15,110.11; nected to the levers meshingwithteeth!arranged on the tyebanas '16, The fee wardends 17 of the levers 1d extend"later.- ally atsubstantially'a right angle, and lia've finger keys l8 fixed thereto;toeXtend movement in the, frame as is usual; Pivoted oblique'angletojthe' levers and the described. i

As stated, it any object oi? the invention to provide an adjustablesupport for the, machine whereby the rear portion of the machine maybetilted upward at variable, angles to the horizontal'to change the focaldistance of the line of'writingjon 'the'platen,

relative to the vision'of the operator;. The

embodiment of. this support-illustrated comp i e P Y t Pi e sees a ged:w th a shoulder intermediate its ends T one end of the pins threaded andengaged 'in openings the s ides machine,

frame and engaged in perforations in angle 7 brackets mounted on a baseboard B by screws engaging in Slots of the brackets, as at 21, andthreaded intothe board. By this arrangement the brackets may be readilyreleased from the pivot pins 19 toremove the-machine from the baseboard. While-the machine is shown and is preferably mounted upon a baseboard whereby the machine' is secured to and supported upon a desk ortable, and which may also serve as a support for an enclosing andcarrying casing for the machine, it will be obvious that the supportingbrackets 20 may be mounted directly upona desk or table. v i

2T0 tilt the rear of the machine upward to a variable extent to inclineobliquely to the horizontal or thebase board a shaft 22- is arranged ina recess 23 extending transverseof the base board androtatably supportedat the opposite ends in recesses in blocks 2% and retained in one blockby a cap plate 25' and thelotherby an angle portion or segment. orsector shape 25, which is arranged With: notches 26 in the circular edgethereof,

7 said segments being secured to the block 24,

as by screws. Angle levers 27 are fixed at one end to the shafts and theopposite ends are arranged as a. hand or finger'grip, 28. These leversare operatively connected to the sidesofthe machine frame by links 29pivotally connected at one end to the frame and at the opposite end to'ears30 extending laterally from the lovers opposite to the,

7 angle portion thereof. In the horizontal pothe levers will assume theposition shown in sition of the machine as shown in Figure 2 said figureand are releasably locked in such position by a detent 81 slidablycarried by oneof the levers engaging with a notch at one endof thesegment25. To tilt therear .portion of the machine upward the detent 31is released by engaging a fingerpiece 32 integral with the detent whenthe levers are movedv forward, as shown in Figures land 4 to 7,inclusive. levers the detent 31 is engaged with the segment notch'at theopposite end of the segment. It will be obvious that the machine maybeadjusted to any desired intermediate position and retained in suchposition by the engagement of the detent 31 with a segment notchintermediate the ends thereof;

fTo facilitateithe lifting :of the'machine meansfare provided toyieldingly urge the mach ne in an upward ClIIGCtIOIL This meanscomprises a pair of springs33 coiled about the shaft 22 with one end ofthe springs secured to a fixed part, as at 3 In this position of thewhile the opposite end is connected to the shaft, in the presentinstance engaging in'a perforation in the levers 27 fixedto the shaftfasa 35, (Figures 4 and 5). The springs 33 also serve'to counterbalance.the

with the keysin alined' horizontal rows extending substantially in thesame plane, and in which position of the keys the typebar levers may beefiiciently operated. Byfthis arrangement of the keys when the machineis tilted upward a'sshown in Figure lthey will assume a position inbanked rows with the tops of the keys in a subtantially horizontalplane. V

While there is illustrated and described one embodiment of carrying outthe invention it will be obvious that various modifications may be madein the construction and arrangement of parts, and portions of theinvention may be used without others and come withinthe scope of theinvention.
